I reset an errant NXT and completed downloading the firmware.  But the NXT still
would not wake up and stayed in Samba mode.

Trying to download firmware immediately after latching the battery pack and
hearing the Samba beat, gives me a "Cannot locate NXT device to download
firmware". Although, Windows Device Manager shows a Lego device plugged in.

If I hit the reset for 20 seconds then download firmware, successful completion
is reported. But still no !Startup jingle and the NXT stays in Samba mode.

In your opinion, is this NXT comatose or brain dead?

It may just need new batteries.  You may want to try putting brand new Alkaline
AAs in it and then press the reset button for a long time (or try using BricxCC
or NeXTTool to put the brick in SAMBA mode).

I'll try the Briccx and/or NeXTTool approach.

Thanks

I've resurrected the "dead" NXT using the standard procedures and my home
computer.  Perhaps, the computers in the lab where smarter than mine.  Mine
performed the download but froze up.  I had to power down and reboot.  All is
fine now, though one begs to ask why it had to be so.

probably some problem with the USB data transfer on your computer,
which corrupted the firmware.  This seems to occur with some computers,
LEGO put out a driver update last year to correct it:

Note that the ticking sound doesn't necessarily mean the NXT is
in Samba mode, it just means that no regular firmware is running.
I.e., the firmware could also have crashed.
